A few days ago, at the end of March, it snowed! Having never experienced snow this late in Hamburg and with the knowledge that 2019 was the second warmest year on record after 2016, my first thought was: this must be the direct cooling effect due to the COVID-19 induced industrial shutdown.

I felt a strange sense of righteousness, as if all climate change skeptics and politicians could now no longer deny the link between economic growth and global warming. This is of course an extremely oversimplified analysis; it is impossible to link two unexpected snow days in Hamburg with a global slowing down in industrial production . Moreover, climate change is a statistically significant variation in “average weather” over a period of 30 years, such that we cannot make any scientifically sound connections between a decrease in greenhouse gas emissions lasting but a few months and global warming.

Nevertheless, the economic shutdown has led to some directly observable environmental benefits.

A while ago, we explained what climate change litigation is, and presented some case examples that have been featured in the media (see here). For this post, we conducted a telephone interview with the climate change litigation expert Gisela Toussaint, who has already been part of several initiatives appealing to different courts. She explains further details of her approach and tells us about her motivation.

Besides demonstrations in the streets and public calls for climate action, activists are also attempting to fight for stricter climate protection laws by employing the legal system. Filing lawsuits against nations and states, political actors or companies in the context of climate change is called climate change litigation. Recently, some cases have gained prominence in German reporting as well as in international media coverage.
